There's something curious about the way crooked penny works now. If you can determine that a particular room will make Crooked Penny fail, such as Hour Glass or the good ol' force-quit, you can guarantee that all adjacent rooms will succeed, and vice versa. As far as I know, that only happens in Repentance. --TheMegax Plus (talk) 21:11, 2 June 2021 (UTC)
